Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187510, here are decompositions:

3 + 187507 = 187510
41 + 187469 = 187510
47 + 187463 = 187510
101 + 187409 = 187510
131 + 187379 = 187510
137 + 187373 = 187510
149 + 187361 = 187510
173 + 187337 = 187510

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 187,510 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
